The power of a light bulb that converts electrical energy at a rate of one hundred joules per second is?

100 joules of energy per second = 100 watts of power


The rate at which an electrical device converts energy from one form to another?

The rate of energy conversion - not just electrical energy, but any type of energy - is called POWER. The SI unit is the watt, which is equal to joules per second.


What is the difference between power and work?

Work is how much energy is transferred, measured in Joules. Power is how fast or slow the work is transfered, measured in Joules per second. One joule per second is called one Watt of power. This meams a 60 Watt light bulb converts 60 joules of electrical energy into roughly 15 joules of light and 45 Joules of heat every second its switched on for.


What do you call to the rate at which an appliance converts electrical energy into other forms of energy?

The rate of conversion of any type of energy is called power. In the international system (SI), the unit for energy is the joule; the unit for power is the watt, which is equal to joules/second.


How many joules of light energy are in 1440 watts of electrical energy?

A joule is a joule, whether it be electrical energy or light energy - although commonly, lamps are not 100% efficient.On the other hand, you can't convert joules directly to watts. Watts means joules per second (joules / second), or equivalently, joules is watts times seconds.A joule is a joule, whether it be electrical energy or light energy - although commonly, lamps are not 100% efficient.On the other hand, you can't convert joules directly to watts.

How many Joules of electrical energy does a 100 Watt light bulb consume from the electrical supply in 2 seconds?

Watt means joules/second. It refers to the amount of energy a device uses, in this case. Multiply the power (in watts) by the time (in seconds) to get the energy (in joules).


Is the length of time an electrical load is on proportional to power or energy?

Power (watts) is amperes times voltage, or joules per second. Energy is joules, or watt-seconds. The length of time an electrical load is on is proportional to energy, not power.


Rate at whth electrical energy is changed to another energy form?

The rate of energy transfer or transformation is mesured in joules / second, also known as watts.The rate of energy transfer or transformation is mesured in joules / second, also known as watts.The rate of energy transfer or transformation is mesured in joules / second, also known as watts.The rate of energy transfer or transformation is mesured in joules / second, also known as watts.


How does watt and joule relate?

The Joule is a unit of energy, while the Watt is a unit of power. Joule is the alternate name for a Newton-meter of energy, and Watt is the alternate name for a Newton-meter per second of power. This means that one Watt is one Joule per second; a 100-Watt light bulb converts 100 Joules of electrical energy every second into heat energy and light energy.


The power of a light bulb that converts electrical energy at a rate of 100 joules per second is?

1 joule is the energy equal to 1 watt for 1 second.100 joules = 100w for 1 second.A 100 watt light bulb converts 100 joules of electrical energy into heat and light every second.Only about 1% of this is useful light, the rest is wasted as heat.AnswerPower is defined as the rate of doing work. As work is expressed in joules (J), it follows that power is measured in joules per second (J/s) -however, in SI, this is given a special name: the watt (W).So one joule per second is exactly equivalent to one watt. Therefore, 100 J/s is exactly equivalent to 100 W.


How many joules equals 1 amp?

This is not a valid question by itself. Joules are units of energy, while Amps are units of electrical current. However, if you also know the Voltage of the electrical current, you can multiply the Current[Amps]*Voltage[Volts] to get the Power in Watts. Watts are equivalent to Joules per second. If you then know the amount of time of the current flow, you can calculate the total number of Joules by multiplying the Power[Watts]*Time[seconds] = Energy[Joules] .


What is the rate at witch electrical energy is converted to another type of energy?

That is called "power". The SI unit for power is the watt, which is equal to joules/second.


How are electrical power and electrical energy related?

Power is always the time-rate of energy, i.e. the rate of change (or transfer) of energy with respect to time.If Energy is measured in Joules, then one Joule being transferred in one second is equal to one Watt of power.Electrical power is the time rate of change of electrical energy, P=dE/dt.Power = energy / timeIt usually referst to some type of energy transfer. In SI units:Watts = joules / second


What unit measures electrical energy consumption?

In physics, the total amount of energy is measured in joules. The rate of energy use - joules/second - is the power, the unit is also known as watt. Electricity companies tend to use another measure for energy use: the kilowatt-hour (kWh), which of course is equal to 3.6 million joules.


State the units of measurement for mechanical energy and electrical power?

The official unit for any type of energy (not just mechanical energy) is the joule. The official unit for any power (not just electrical power) is the watt, equal to joules / second.


What is it called when you measure of how much electrical energy carries electrons?

Electron flow is current, or coulombs per second. Electron potential is voltage or joules per second.


What is electricity measured?

Electric power (how fast energy is being converted into or out of electrical energy) is measured in Watts. Electrical energy is measured in Joules. i Watt for 1 second is 1 Joule. 1000 Watts for 3600 seconds is 3.6 Megajoules, also known as a kilowatt-hour or a Unit of electrical energy.


What is the rate at which a device converts electrical energy to another form of energy?

That is called power. The SI unit is the watt. 1 watt = 1 joule/second.


What is the power of an electrical cable car that uses 3500 joules every second?

3500W, or 3.5kW Power is measured in Watts; one Watt is 1 joule of energy converted/used per second. So, 3500 joules a second is 3500 Watts.


What is the energy used in one second when a bulb have 40Watts.?

40 Joules, I think, as the formula for Watts is Joules/Second = Joules per second 40 Watts should equal 40 Joules per one second...


What is the amount of electrical energy used in a certain amount of time?

Joules. One joule is one watt for one second. We commonly use kwh, or kilowatt-hours, that is simply 3.6 x 106 joules.


How much electrical energy in joules does a nuclear power reactor generate in one day?

A typical nuclear plant can run continously at 600 MW, which 6 x 108 Joules per second or, per day, 5.184 x 1013 Joules.


Does a 150 watt bulb do 150 joules of work?

Every second a 150 Watt bulb converts 150 Joules from electricity into heat and light. The number of Watts tells you how many Joules pass per second.


What is the rate at which electrical energy is converted to another type of energy?

The rate of energy transfer - any type of energy transfer, including this specific case - is called the power. The SI unit is the watt, which is equal to joules/second.


How much electrical energy does a 100W lamp use in 1 second?

Watts measure power. Energy is measured in joules and is the product of power and time. 1 joule = 1 watt for 1 sec Energy used in the example = 100 x 1 = 100 joules
